Adelaide café serves up coffee with 80 times more caffeine than usual

An Adelaide café has begun serving up an iced coffee with 80 times more caffeine than a regular espresso.

Christie’s Beach café Viscous Coffee has started selling the ‘Asskicker’ iced coffee, which contains five grams of caffeine, The Advertiserreported.

The fully charged beverage has half the lethal dose of caffeine.

It is created using four shots of espresso, eight frozen cubes of ‘cold drip’ coffee – which each contain the caffeine equivalent of more than two shots of espresso – and some 10-day brewed liquid cold-drip coffee.

Viscous Café owner Steve Benington told The Advertiser he originally devised the beverage for an emergency department nurse who needed to be kept awake for an overnight shift.
